Lines of evidence: The science of evolutionThe theory of evolution is broadly accepted by scientists — and for good reason! Learn about the diverse and numerous lines of evidence that support the theory of evolution.

Webcast: Fossils, genes, and embryosIn lecture three of a four part series, evolutionary biologist David Kingsley examines the original objections to Darwin's theory and shows how modern evidence supports the theory.This lecture is available from Howard Hughes' BioInteractive website.

Darwin's "extreme" imperfection?Darwin used the words "extreme imperfection" to describe the gappy nature of the fossil record - but is this really such a problem? This article delves into the topic of transitional fossils and explores what we have learned about them since Darwin's time.This article appears at SpringerLink.

15 evolutionary gemsThis succinct briefing describes 15 examples drawn from recent research that demonstrate evolutionary theory’s power to explain natural phenomena, along with some of their supporting lines of evidence--from whale fossils to the latest in genetics.This resource is available from Nature magazine.

Evolutionary medicineThis excerpted chapter from Carl Zimmer’s book, The Tangled Bank, describes how evolutionary biology informs and advances medical science. Reprinted with the permission of Roberts and Company Publishers, Inc.

Sound treesStudents learn how spectrograms represent sound variation and then examine the sounds of owls for traits that might be useful in determining evolutionary relationships. They compare these traits to morphological ones and test their hypotheses.

Born to Run: Artificial Selection LabStudents are introduced to the field of experimental evolution by evaluating skeletal changes in mice that have been artificially selected over many generations for the behavioral trait of voluntary exercise wheel running
